Adds a "Build a customer support chat agent" guide to the AI agents
section, surfaces the ClickHouse chat agent example in the guides index
and the AI agents overview, and refreshes the five existing workflow
guides so their code is current.
The pattern guides (prompt chaining, routing, parallelization,
orchestrator, evaluator-optimizer) still used retired models and dated
APIs. Updated them to current Anthropic Claude models (claude-haiku-4-5
for lightweight classifier roles, claude-sonnet-4-5 for the main work)
and modernized the code:
- route-question uses generateObject for the routing decision instead of
generateText plus manual JSON parsing.
- verify-news-article uses ModelMessage in place of the renamed CoreMessage.
- Fixed translate-and-refine discarding its recursive refinement result,
so refined translations never returned to the caller.
- Fixed an invalid JSON test payload in generate-translate-copy.
The pattern concepts are unchanged; only the example code was stale.
